Has anybody considered using an electromagnetic clutch? I've seen all kinds of 'em used on machinery. Pneumatic clutches too. Torque limiting sprockets may give you the break-away that you need during lock-up.

If you really only care about an emergency disconnect then I would think an appropriate sized contactor or switch is a simpler solution. I have one of these circuit breakers in my truck http://www.electroauto.com/catalog/circtbkr.shtml. You could mount it anywhere you have room and run your clutch cable to it to manually trip it. damon > To: [email protected] > From: [EMAIL PROTECTED] > Date: Sun, 6 Jan 2008 22:06:43 -0500 > Subject: [ElectricMotorcycles] To clutch or not to clutch > > > *There's a constant debate on the EV list (a list which I sadly had to > > admit I don't have time for any more) about running clutchless. > > > > I'm not planning to use the stock trans and clutch, I'd rather use > the space for batteries. > However I keep thinking that the second thing you reach for when the > throttle jams (after the kill switch) is the clutch. > The stock clutch lever is already in a familiar place I just need > something lighter and simpler than the stock wet clutch. > Could be a much more basic device since you don't need to slip it on > takeoff, maybe a dog clutch rigged as a mechanical disconnect. > A lot of the car conversions have big contactor cut-outs to cut the > power to the motor in case of a run-away, I don't know if a > mechanical cut-out would be easier or cheaper. > > Andrew in Ann Arbor > ------------------------------------------------------------------------------ Put your friends on the big screen with Windows Vista® + Windows Live™.
